ROTARY MACHINE.

(4!! whom it may concern le 1t known that l, KARL Krrlrna, a citi-'Ifill of the United States. residing at Cincinnati. in the county ofHamilton and State of Ohio. have invented certain new and usefulimprovements in Rotary B'Iachines, of which the following is aspecification;

)Iy invention relatesto improvements in machinery in which an operatinghead rotates, carrying a number of operating elements. together with anumber of lifting elements presenting the articles to :be operated upon.these lifting elements being raised and lowered during such rotation.

The objects of my invention are to save time and avoid friction in theoperation of the machine, and to provide adjustments for such a machinemaking it readily adaptable for operatingon articles of different sizesand shapes.

Myimprovements are especially desirable in the construction andoperation of bottlefilling machines.

it is also readily applicable to other ma-' chines operating upon theci'ples above set forth. 1

I attain these objects by the mechanism illustrated in the accompanying(lawings, in which Figure l is an upright view of a bottle fillingmachine embodying my improvement, showing however, for the sake ofsimplicity, only three bottle tables; Fig. 2 is a horizon- 'tal view ofone of the bottle tables; and, Fig. shows another vertical view With apartial cross section through some of the parts of the machine. F ig'. lis a detail View of the composite gearwheel.

Similar letters :refer to similarparts throughoutthe several views.

The filling machine is mounted upon a substantial base A, Fig. 3,rigidly attached to which is a tubular for a bearing for all therotating parts of All the rotating parts are mounted on a heavy casttubular part 3, that finds its bearing upon tube 2, which tubular partis set in motionby a worm and worm wheel at and 5 respectively, thelatter rigidly attached to the tubular part The filling head, by whichword I designate the filling apparatus proper and which I will call B,in its rotation is carried by a tubular screw 6 that is held Securely'bythe general prin- Specification of Letters Patent.

threaded for this purpose. A lock screw 8,

will clamp the filling head in any position so as to be rigidly attachedto the tube 3 and rotate therewith. Attached to the tube 3 is a. table 9having apertures 16 corresponding in number with the number offillingvtubes. Below is another disk-shaped holder 10, also securelyfastened on the tube 3, and providing another set of bearings for thebottle table lifters, as will be described later on.

In order to adjust the machine for the dift'erent heights of bottles, Iscrew the filling head more or less into the threaded part of the tube3. It is necessary, however, that bottles of different sizes, especiallydifferent diameters, should be brought centrally below the filling tubeof the filling head, and

for this purpose the bottle tables,-as shown at an angle of about 120degrees in the di Upon this table 2, Fig. 2, dotted circles are drawn 12and 13, these circles representing different sizes of bottles. If suchbottles are pressed against the angle-shaped border 11, their centerswill approximately fall in line with the dotted line indicated by#145-which approximatelycorresponds with the linebisecting the angleformed'by the twohalves of the border. It is necessary in the fillingoperation that these bottles. should therefore be pressed against thisborder 11, in order to insure the placing of the bottle in the centerline marked 14, this center line 14 lead ing through all centers of thefilling tubes.-

In order-to also'c'entei thebottlc radially, i

it is necessary that when screwing thefilling head into the tube 3 bymeans of the threaded part 6, the filling tube should be stopped and thefilling head fastened by means of the lock screw 8, so as to allow forthe difference in diameters of the bottles, which will be easilyunderstood from the drawing, Fig.

2. .In this figure the two circles indottcd lines represent bottles ofdiflerent-diarigeters.

Should the bottle table be stationar I 3P? proximately under the centerof the 7 of the machine would not be filling i tube, the small bottle,indicated byfth aillotted would be somewhat aside ojf the center, and anaccurate workingadjustment or other operating elements, in the head B,

are stopped over the respective centers of the small bottles. \Vhen thisadjustment is completed, the head 13 is locked in its position by meansof the screw 8.

The table lifting mechanism is easily visible in Fig. 1. A strong rod 15carries at its upper end the bottle table, and slides in bearings 16contained in the table 9. It carries a casting on its lower end, havinga rack 17 and a roller 18,at its lowest end. This of the composite gearwheel 20, journaled on casting is of elongated slotted formation,- andthe slot serves as a second guide by receiving the guide roller 19,which forms part a stud in the holder 10. This gear is composed of aspur part 20 and a bevel part 20". The spur part 20, which lies next tothe guide roller part 19, is in constant mesh with the rack 17 of thecasting above described, while the bevel part 20 periodically mesheswith the segmental rack 21, mounted on the base A of the machine. Thecomposite gear is well illustrated in Fig. 4, and the co-action of theparts will be readily understood from the following explanation.

In Fig. 1, gear 20 is in constant mesh with rack 17. Rack 17 is at itslowest point now, and the roller 18 is rolling at its lowest point on atrack 22. The segmental rack 21 is of.

the approximate length of the rack 17, and

it is supposed that the operation of the machine, m drawing Fig. 1, isfrom right to left. The mechanism is in the position of the gear 20 juststarting to come into mesh with the segmentalrack- 21; the action of themechanism will be that as the gear 20 will rotate counter-clockwise,rack 17 will be moved upward and a bottle Will be lifted.

The track 22 is in inaction, but as soon as the bottle is at its fullheight, the roller 18 will find a new section of the track, marked 23,to roll upon, which track will hold the bottle in its upper positionduring the operation of filling, and until it drops back into its lowestposition when coming over the lowest partof the track 22. o

By means of my arrangement a great deal of friction that has heretoforebeen-incurred by inclined tracks is avoided, and the table can be liftedvery rapidly at any desired angle. I
